IntEnz Enzyme Nomenclature
EC 1.1.1.319

Names

Accepted name:
isoeugenol synthase
Other names:
IGS1
t-anol/isoeugenol synthase 1
Systematic name:
eugenol:NADP+ oxidoreductase (coniferyl acetate reducing)

Reactions

Comments:

The enzyme acts in the opposite direction. In Ocimum basilicum (sweet basil), Clarkia breweri, and Petunia hybrida only isoeugenol is formed [1,2]. However in Pimpinella anisum (anise) only anol is formed in vivo, although the cloned enzyme does produce isoeugenol [3].
